I have to pay this parking charge, don't I.

Actually, the law did change last year and whilst previously it was unenforceable because if the registered keeper claimed not to have been driving, they couldn't pursue them. The government changed the law (thanks Tories ) so that now they can pursue the registered keeper regardless. Whether this will translate into prosecutions is unclear at the moment.

I got one earlier in the year and given the change in the legal situation, decided it wasn't worth just ignoring it. I contacted the supermarket where I had been (Aldi) to complain and they asked me for bank statements or receipts either showing that I had been shopping there on the day in question, or just that I did so on a regular basis. I did this and they immediately cancelled the charge. I would say it's worth a go at complaining to the supermarket in question and seeing whether they will waive it.

Really?! There was a blurb about the law changing last year and how they can pursue me as the car owner to pay that, even if I wasn't the driver (which I was). What if they send debt collectors to my place?

Just checking in case I don't but I doubt it. Parked un a supermarket car park for an hour and a half. Got a letter today saying I need to pay fine as there was a sign saying you can only park for an hour for free. I didn't see the bloody thing and now they say I need t o pay £70 or £40 if paid in the next 10 days.
